The volume of a rectangular prism is 72 cubic centimeters. The prism is 2 centimeters wide and 4 centimeters high. What is the l

skelet666 [1.2K]

Answer:

The length of prism is <u>9 centimetres</u>.

Step-by-step explanation:

Given:

The volume of a rectangular prism is 72 cubic centimeters.

The prism is 2 centimeters wide and 4 centimeters high.

Now, to find the length of prism:

Let the length be $l$ .

Width = 2 centimeters.

Height = 4 centimeters.

Volume = 72 cubic centimeters.

So, putting the formula to get the length of prism:

$Volume = length\times width\times height$

$72=l\times 2\times 4$

$72=l\times 8$

Dividing both sides by 8 we get:

$9=l$

Length = 9 centimetres.

Therefore, the length of prism is 9 centimetres.

The diagram below shows an Isosceles triangle. Label the base angles and the vertex

Anna007 [38]

The measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

Find the diagram attached.

The base of the isosceles triangle is "b".

Since the base angles are equal, hence the sum of the interior angle is expressed as:

b + b + 112 = 180

2b + 112 = 180

2b = 180 - 112

2b = 68

b = 68/2

b = 34 degrees

Hence the measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

Would appreciate it, if anyone could help with this.

Tema [17]

Since they are intersecting lines, you would equal them to each other.
(5x+4)= (8x-71)
-8x. -8x
-3x + 4 = -71
- 4. -4
-3x = -75
Divide 3x by both sides gets you x = 25
